The new Atlas Gunworks AlphaLock 2011 magazine basepads are a great upgrade for any magazines or magazine tubes you may have in need of some parts! For optimal capacity, use the 4mm basepads with 140mm/20 round tubes (if using Atlas tubes, you can use this with their 170mm/26 round tubes) and the 3mm basepads with 170mm/26 round Checkmate/Staccato tubes.
We have verified these will fit and function with:
- Atlas Gunworks
- Checkmate/Staccato/Kimber
- Prodigy/Duramag
Disclaimer: Due to tolerance stacking, we do not guarantee any 20 round/140mm magazines to pass the USPSA 141.25mm gauge. Verify your magazine length with a certified magazine gauge and fit the magazine as appropriate to be legal for your division.

Perfect Zero / Atlas Basepad
I initially ordered 6 and they were very easy to install and I really liked the clasp design. Note: I put these on 20 Round Checkmate mags with no issues.
